So I just had a curiosity question pop up and wanted to check it out. Solr has the documentCache, designed to hold stored fields while various parts of a requestHandler do their tricks, keeping the stored content from having to be re-fetched from disk. When using MMapDirectory, is this even something to worry about?
It seems like documentCache wouldn't be all that useful, but then I don't have a deep understanding here. I can imagine scenarios where it would be more efficient i.e. it's targeted to the documents actually being accessed rather than random places on disk in the fdt/fdx files.... Thanks, Erick
